While she wasn't part of the original roster of people permitted citizenship on Mountain Viewtopia's Launch Day, her presence was requested somewhat last-minute as an accommodation for Ravi Helton. As his oldest friend, Su has helped Ravi stay in touch with reality given that the circumstances of his life have always been extreme compared to the average person. But there's a lot more to Su than her relationship with some boy! (I mean, he may be one of the bestest boys there is but, even still, she's her own lady whose life isn't defined by a man.)
Su's technical expertise is about as extensive as you can get. She can invade virtually any computer system.
Su likes wearing comfortable clothing, rocking out to rap music, and getting lost in the pages of entertainment magazines. Even so, she doesn't enjoy watching adventure films, having anything to do with war movies, or reading dumb autobiographical material. Typically, you'll encounter Su re-reading False Impressions, bathing in the aural auras emanating through the sensuous music of TheOvertunes, and eating melons.
Su has a relentless interest in experimentation, by the way. She will try almost anything and loves to talk about it. This works great for me because he usual dialogue with other people is already in a format that I find very easy to parse. This can lead her to trying some unusual things (e.g. potato salad) but, overall, she's collected a lot of useful information about things like dart boards and the varying flavors of mouths.
Su is enamored with that episode of Color Sample Wars with Winter's Breeze and Carribean Green since Carribean Green had a bad match with a traffic cone.
